GEODE-8548: Avoid hostname resolution in TcpConn (#659)
- Calling get_host_name() in TcpConn::connect involves a system call that
might take several seconds to complete.
- So endpoint is stored instead upon TcpConn construction and used later
instead of making the system call.
- (pdxcodemonkey) Note that the call in question was buried in use of a LOG*
macro, which is not best practice
> ACE_Inet_Addr takes too long in reverse DNS resolution

> Project: Geode
> Issue Type: Bug
> Components: native client
> Affects Versions: 1.11.0, 1.12.0, 1.13.0
> Reporter: Mario Salazar de Torres
> Assignee: Mario Salazar de Torres
> Priority: Major
> Labels: connections, pull-request-available
>
> Whenever TcpConn::connect is called, a system call to *get_host_name* is made
> in order to obtain reverse resolution for the connection address, right here:
> {code:cpp}
> void TcpConn::connect() {
> using apache::geode::internal::chrono::duration::to_string;
> ACE_OS::signal(SIGPIPE, SIG_IGN); // Ignore broken pipe
> LOGFINER(std::string("Connecting plain socket stream to ") +
> inetAddress_.get_host_name() + ":" +
> std::to_string(inetAddress_.get_port_number()) + " waiting " +
> to_string(timeout_));
> ยทยทยท
> {code}
> get_host_name executes getnameinfo underlying and the thing is that depending
> on your system configuration in the case of the address not having a reverse
> resolution entry it might take a long period. In my case it takes 10 seconds.
